I need food!
Anything Goes
100
The model of the feeding relationships between many different consumers and producers in an ecosystem
What is a Food Web?
100
Sun, water, air and soil are these types of factors in an ecosystem
What are Abiotic Factors?
100
This process in the water cycle occurs when water heats up becoming a gas and rises in the air.
What is evaporation?
100
Organisms that make their own food through photosynthesis or chemosynthesis are known by the names of producer or this name.
What are autotrophs?
100
These organisms determine the types of animals that can live in an ecosystem.
What are plants/producers?
200
Shows the feeding relationships between a single producer and several consumers
What is a Food Chain?
200
Microorganisms, plants and animals are these types of factors in an ecosystem
What are Biotic Factors?
200
This process in the water cycle occurs when water vapor changes back into liquid and collects in clouds.
What is condensation?
200
Organisms that eat other organisms to get the energy they need are called consumers or this other name.
What are heterotrophs?
200
The name of the process in which producers deep in the ocean produce their own food using chemicals that rise out of heated vents.
What is chemosynthesis?
300
The name for the first level of organisms in a food chain
What is a producer?
300
Bacteria and worms play this role in an ecosystem.
What are Decomposers?
300
This element is believed to be primarily responsible for global warming due to its rising levels in the atmosphere.
What is carbon?
300
In an ecosystem, all dying consumers and producers are sources of food for these organisms.
What are decomposers?
300
This gas makes up about 4/5 or 80% of the air we breathe.
What is Nitrogen?
400
The arrows in a food web and chain represent this.
What is the flow of energy?
400
The level of an energy pyramid with the most available energy.
What is the bottom level (Producers)?
400
These two things have the ability to "fix" Nitrogen gas so that it is usable to plants.
What are bacteria and lightening?
400
Green plants need these 3 things to make their own food in a process called photosynthesis.
What is sun, water, and Carbon Dioxide?
400
The names of the two gases that are exchanged during animal respiration.
What are Oxygen and Carbon Dioxide?
500
A lion that eats a fox that eats a rabbit that eat eats grass is at this level in a food chain.
What is Tertiary Consumer?
500
The amount of energy available to the level just above a level with 100% available energy
What is 10%
500
The name given to the process that occurs when plants release water vapor into the air.
What is Transpiration?
500
The name of the model that shows the amount of energy available at each feeding level of an ecosystem.
What is an Energy Pyramid?
500
The name of the most common producers found in a water ecosystem.
What are phytoplankton?
